How to maximize the browser window in Selenium WebDriver (Selenium 2) using C#?

Question

Is there any way to maximize the browser window using WebDriver (Selenium 2) with C#?

Answer 1

This is working fine for me.

Capybara.current_session.driver.browser.manage.window.resize_to(1800, 1000)

Answer 2

I tried many of the answers above, but none work well. My chrome driver version is 2.7 and Iam using selenium-java vesion is 2.9.0. The official document suggests using:

var capabilities = new DesiredCapabilities();
var switches = new List<string>
                       {
                           "--start-maximized"
                       };
capabilities.SetCapability("chrome.switches", switches);    
new ChromeDriver(chromedriver_path, capabilities);

The above also does not work. I checked the chrome driver JsonWireProtocol: http://code.google.com/p/selenium/wiki/JsonWireProtocol

The chrome diver protocol provides a method to maximize the window:

/session/:sessionId/window/:windowHandle/maximize,

but this command is not used in selenium-java. This means you also send the command to chrome yourself. Once I did this it works.

Answer 3

For me, none of the solutions above worked when working with Selenium Web Driver C# + Chrome:

• window.resizeTo(1024, 768); - I want to use the whole screen
• --start-maximized - it is ignored
• driver.manage().window().maximize(); - does not work because it requires some extension and I am not allowed to use Chrome extensions

I managed to get it working using InputSimulator:

var inputSim = new InputSimulator();
// WinKey + UP = Maximize focused window
inputSim.Keyboard.ModifiedKeyStroke(VirtualKeyCode.LWIN, VirtualKeyCode.UP);

Answer 4

Simply use Window.Maximize() command

WebDriver driver= new ChromeDriver()
driver.Manage().Window.Maximize();  

Answer 5

For C#:

driver.Manage().Window.Maximize();

For Java:

driver.manage().window().maximize();

Answer 6

For Java:

driver.manage().window().maximize();

It will work in IE, Mozilla, Chrome
